Dry building mixtures are widely popular in the construction and renovation industry. They are easy to prepare and apply. Dry mixtures belong to the group of auxiliary building materials that are used for internal and exterior finishing premises. Immediately after dilution with water, they become suitable for use and are used for plastering, laying tiles, brickwork, etc. Precise dosage of all components of the composition and compliance with the rules for mixing the starting raw materials make it possible to obtain high-quality solutions for use in different areas construction.

Classification of dry mixtures for construction

Modern mixtures are used for various types works, therefore they are usually divided into:

• masonry – thick-layer and thin-layer;
• adhesive – mounting, facing. Used for laying tiles and porcelain tiles, aerated concrete blocks, bricks, etc.;
• floor - for leveling, making screeds, creating a finishing layer. They are ordinary and self-leveling;
• repair - injection, volumetric - and surface-restorative;
• insulating – used to create heat and sound insulation;
• plastering – light, special and heavy;
• putty – leveling and to create a finishing layer;
• grout - for grouting joints up to 6 millimeters thick, and joints more than 6 millimeters wide;
• universal - mixtures that can be used for various construction and repair work.

Dry mixtures are also classified by composition binder- they can be simple and complex. To create simple mixtures, only one binder is used, for example, cement or gypsum. In complex mixtures, several binder additives are used simultaneously.

In addition, dry mixtures are divided into special and universal, which can be used for most repair and construction work. So, for example, leveling mixtures for putty are often used when pouring the floor, starting finishing wall panels etc.

Dry mixtures are used for both internal and external works. When carrying out work inside buildings, gypsum mixtures are most often used, thanks to which a microclimate favorable for humans is maintained in the room. When carrying out external work, mixtures are used that are based on cement - a substance that is highly resistant to moisture, fire-resistant and resistant to atmospheric conditions.

Dry mixtures are classified according to the dispersion of the filler - they can be finely dispersed - the filler fraction does not exceed 0.315 mm, and coarse - the fraction is 2.5 mm and above.

Composition of dry mixtures

The basis of the mixtures can be gypsum, polymers and cement; various additives are also added to them, giving the composition the necessary quality characteristics. Substances used in the production of dry mixtures are conventionally grouped into several groups:

• Mineral binders - lime, Portland cement, gypsum.
• Organic binders are polymer powders based on ethylene, vinyl chloride, acrylate.
• Fillers – chalk, quartz sand, amorphous silica, talc, asbestos, vermiculite.
• Water-retaining additives, plasticizers and substances that regulate the setting of the material.

Binders are added to mixtures in order to increase their strength characteristics and adhesion. A distinction is made between hydraulic and non-hydraulic components. Hydraulic ones give the mixture high resistance to water.

Modified additives for dry construction mixtures

Thanks to the use of modifying additives, dry mixtures for construction acquire the necessary specifications. In dry mixtures, the proportion of modifying additives is about fifteen percent. Modifying additives can be of organic or inorganic origin. They increase the connection of components with water and improve its adhesion characteristics. Additives regulate spreading and are responsible for plasticity and durability during further use.

Scope of use of dry mixtures for construction

Dry mixtures can be used in almost all types of work related to the construction and renovation of premises. So, for example, the M150 mixture, created on the basis of sand and Portland cement, is used:

• for processing joints and seams;
• laying bricks, porcelain stoneware, paving slabs;
• when conducting plastering works;
• for leveling any surfaces;
• when concreting stairs;
• during the repair of floors and other reinforced concrete structures.

The M150 mixture is quickly applied to the surface and hardens within 24 hours.

Dry mixture M200 can be used for laying bricks and aerated concrete blocks, pouring foundations, and when carrying out plastering work. It contains Portland cement, sand, and modified additives. The mixture was created taking into account the requirements of GOST 28013-98. Material consumption is 10 kg per 1.9 liters of clean water.

M300 is a self-leveling mixture, the main difference of which is its fast hardening time. It is used not only for leveling floors, but also for pouring foundations, load-bearing structures, brickwork, fastening reinforced concrete structures. The M300 mixture is characterized by maximum strength indicators, resistance to high humidity and temperature changes.

Advantages of dry construction mixtures

Due to their special composition and ease of preparation, building mixtures are widely popular in the construction industry. The main advantages of dry mixtures include the following factors:

• Easy to use and prepare - the packaging of each mixture contains instructions, following which you can obtain a high-quality and ready-to-use solution.
• Stability of the composition - all components are added to the dry mixtures in strictly dosed form, so any composition retains all the specified characteristics.
• Cost-effective – the use of building mixtures helps to save costs, since the solution is applied in a thinner layer. In addition, the time spent on finishing is significantly reduced, which is important.
• Uniformity and plasticity - if the instructions are followed, the solution turns out to be homogeneous and can be applied well to any surface.
• High adhesive qualities – reliable adhesion to almost any base.
• Excellent sound and heat insulation properties.
• Long shelf life – even with long-term storage mixtures do not lose their original characteristics. They can be transported and stored even at low temperatures.
• Environmentally friendly - all mixtures intended for repair and construction are absolutely safe for human life, therefore they can be used for both external and internal work.

When choosing mixtures for work, it is best to follow the rule of choosing materials from one manufacturer - they are perfectly combined with each other, guaranteeing quality and long term operation.
